IsoMon Dual-Channel Gas Detection

ATi’s IsoMon Dual-Channel Gas Detection system monitors complete decontamination processes from start to finish, measuring both high and low gas concentration levels.

Dual channel gas monitoring for high & low levels

ATi’s IsoMon dual-channel gas detection system has revolutionised the way sterilisation cycles are processed, monitoring the complete decontamination process from start to finish and measuring gas levels of both high and low concentration.

This unique system has been primarily developed to address the sterilisation needs of the pharmaceutical, biological, medical device manufacturing, defence, industrial, healthcare and food packaging industries, but can also be deployed to reduce the occurrence of hospital-acquired infections and even the decontamination of aircraft cabins.

IsoMon is a first-of-its-kind gas detector that allows both high and low value measurements of Hydrogen Peroxide levels, providing users with reliable validation data regarding the sterilisation of aseptic environments and that they are safe following sterilisation.

Hydrogen Peroxide & Peracetic Acid Monitoring

Discover how ATi’s PharmaSafe range of fixed and portable gas detectors validate cleaning processes, prove efficacy, monitor residual gas levels and provide an audit trail, whilst helping to keep staff safe.



Yes, the ATi H10 smart gas sensor can be plugged into any compatible gas detection device. Also multiple sensors can be used on one device, resulting in a gas detector that can go from measuring Phosgene to Ammonia in less than one minute.

We recommend that the H10 smart gas sensor is calibrated every 6 – 12 months, however this may vary depending upon which gas is being monitored.
